Jovian planets are those planets consisting almost entirely of gas, notably hydrogen and helium, with a mixture of other volatile gases like ammonia and methane. Within our own solar system, the Jovian planets are Jupiter, Saturn, Uranus, and Neptune.

Jovian Planets
The Jovian planets are , , , and . They are also called the or . There are four major condensable (cloud forming gases) in these planets. The ones with the highest saturation vapor pressure will condense at the highest altitudes.

Jovian Planets
Because the physical and chemical properties of Mercury, Venus, and Mars are somewhat similar to Earth's, the four innermost planets are called the terrestrial planets.

Jovian Planets
The planets Jupiter, Saturn, Uranus, and Neptune. They are called Jovian planets because of similarities in their composition and location.

The Jovian Planets
Jupiter, Saturn, Uranus, and Neptune are known as the Jovian (Jupiter-like) planets, because they are all gigantic compared with Earth, and they have a gaseous nature like Jupiter's.

The jovian planets are made of lighter materials that exist under much higher pressures than can occur anywhere on the Earth. Direct observations of their structure are still limited to the top several hundred kilometers of their atmospheres.

The jovian planets are located far from the Sun, so their satellites tend to be made of common materials found at these distances.

Did the Jovian planets form from accretion or merely coalesce? After all, the Sun coalesced from gases. It's hard to say today, but future explorers may find out.

Mission: Jovian planets and interstellar space.
Features: The Voyager 1 and Voyager 2 spacecraft were launched in late 1977 aboard Titan III launch vehicles with Centaur upper stages.

Like the other jovian planets, Saturn has a significant magnetic field.

The four outer planets, or gas giants, (sometimes called Jovian planets) are so large they collectively make up 99 percent of the mass known to orbit the Sun.

The four outer planets, or gas giants (sometimes called Jovian planets), collectively make up 99 percent of the mass known to orbit the Sun. Jupiter and Saturn's atmospheres are largely hydrogen and helium.

Usually in plural Jovian planets. JP (abbr) (NASA SP-7, 1965) = jet propulsion
Compare RP (abbr). JP-4 (NASA SP-7, 1965) A liquid fuel for jet and rocket engines, the chief ingredient of which is kerosene.

The ices which formed the Jovian planets were more abundant than the metals and silicates which formed the terrestrial planets, allowing the Jovian planets to grow massive enough to capture hydrogen and helium, ...

Also called Jovian planets. gibbous (NASA SP-7, 1965) Bounded by convex curves.

It is not clear why Uranus has such a low internal heat output compared to the other Jovian planets. All the planets should have started warm, when gravitational energy was transformed into heat during planetary accretion.

Once believed to be the only planet to have rings, we now know that all four of the Jovian planets (Jupiter, Saturn, Uranus, and Neptune) have ring systems. The ring system of Jupiter, however, is only 1/1000 as bright as the rings of Saturn.

In various instances now we know that ring structures in the Jovian planets are stabilized by small "shepherd moons" that orbit in or near the rings and stabilize them by their gravitational influences.

In our Solar System, the gas giants (also called the Jovian planets) are Jupiter, Saturn, Uranus, and Neptune.

All jovian planets in the solar system have rings. They may form by the breakup of a moon that came within the planet’s Roche limit or from particles that were originally there.
